SML/NJ for School and Home

Standard ML of New Jersey provides a free alternative implementation
with only minor deviations from the revised
definition and the standard
library. However, it does not provide an X interface, browser, or other
tools available with MLWorks.

To use SML/NJ from Suns in an Andrew cluster, type:/usr/contributed/bin/sml
It may become available as /usr/local/bin/sml for this and
other platforms during the semester

On Suns and other Unix machines, you may run the CS installation of SML/NJ with /afs/andrew/scs/cs/15-212-ML/bin/smlnj
